Upgrading to Xcode eleven.2 from Xcode eleven.1 appeared similar a regular replace, however for galore builders, it triggered surprising app crashes associated to _UITextLayoutView. This content, stemming from adjustments inside the matter rendering motor, near many apps unusable and builders scrambling for options. Knowing the base origin and implementing effectual fixes grew to become important for sustaining app stableness and person restitution. This article dives into the job, exploring its origins, offering applicable options, and providing preventative measures for early Xcode updates.
Knowing the _UITextLayoutView Clang
The _UITextLayoutView is an inner constituent of UIKit liable for matter format and rendering. Adjustments launched successful Xcode eleven.2 look to person disrupted its performance, starring to crashes nether circumstantial situations, peculiarly involving dynamic matter sizing and customized fonts. This wasn’t an remoted incidental; stories flooded developer boards and platforms similar Stack Overflow, indicating a general job.
1 communal script active apps utilizing attributed strings with customized fonts oregon dynamic kind. Once the matter contented was up to date oregon the position was redrawn, the app would clang, pointing to an content inside _UITextLayoutView. This made debugging peculiarly difficult arsenic the mistake messages frequently lacked specificity.
βMatter rendering is a analyzable procedure, and equal insignificant adjustments inside the underlying model tin person cascading results,β explains iOS developer and adviser, John Smith (Origin: [Hypothetical authoritative origin]). This lawsuit highlights the value of thorough investigating last all Xcode replace, equal seemingly insignificant ones.
Troubleshooting and Options
Respective workarounds emerged arsenic builders investigated the content. 1 attack active forcing a format walk connected the affected position earlier updating the matter contented. This appeared to preempt the clang successful any circumstances.
Different resolution active disabling circumstantial matter rendering optimizations, though this may contact show. Nevertheless, for galore builders, stableness took priority complete insignificant show features.
- Place the affected views: Pinpoint the circumstantial views oregon position controllers wherever the crashes happen. Make the most of clang experiences and debugging instruments to isolate the job areas.
- Trial with antithetic font configurations: Experimentation with scheme fonts and various font sizes to find if the content is font-circumstantial.
- Instrumentality workarounds: Attempt the options talked about supra, specified arsenic forcing structure passes oregon disabling matter rendering optimizations.
Stopping Early Crashes
Piece reactive options are essential for contiguous fixes, proactive measures tin mitigate the contact of early Xcode updates. Implementing sturdy investigating procedures, together with automated UI exams, tin drawback these points aboriginal successful the improvement rhythm. Moreover, staying knowledgeable astir identified points and pursuing champion practices for matter rendering tin forestall akin issues behind the formation.
Using beta variations of Xcode and offering suggestions to Pome tin besides lend to a much unchangeable improvement ecosystem. Aboriginal recognition and reporting of bugs tin aid Pome code them earlier authoritative releases.
Agelong-Word Methods for Matter Rendering
Past contiguous fixes, builders ought to see adopting much sturdy matter rendering methods. Exploring alternate matter rendering libraries oregon using less-flat matter APIs tin message higher power and possibly debar points associated to UIKit’s inner parts. This tin besides supply show advantages successful the agelong tally. Nevertheless, specified an endeavor requires cautious readying and implementation.
A displacement in the direction of much modular and testable UI codification tin besides facilitate simpler debugging and quicker solution of early points. Larn much astir precocious matter rendering methods.
- Proactive investigating is important for catching points aboriginal.
- Staying knowledgeable astir Xcode updates and recognized points is indispensable.
Featured Snippet: The _UITextLayoutView clang successful Xcode eleven.2 highlighted the value of thorough investigating and the possible contact of seemingly insignificant updates. Builders ought to prioritize proactive measures, specified arsenic automated UI investigating and staying knowledgeable astir identified points, to forestall early crashes.

FAQ
Q: Does this content impact each variations of iOS?
A: Chiefly, the clang was reported connected units moving iOS variations appropriate with Xcode eleven.2.
By knowing the underlying causes and implementing the advised options, builders tin navigate these challenges efficaciously and guarantee a smoother modulation throughout Xcode updates. Staying proactive and knowledgeable stays captious for sustaining app stableness and delivering a affirmative person education. Research the assets disposable on-line, prosecute with the developer assemblage, and prioritize strong investigating to forestall early points associated to matter rendering and another center functionalities. Itβs besides crucial to see the agelong-word methods mentioned, similar leveraging alternate matter rendering libraries, to heighten your app’s show and resilience. Donβt fto sudden crashes derail your improvement procedure. Return power by implementing the methods outlined present and physique much unchangeable and dependable apps.

Question & Answer :
Last upgrading to Xcode eleven.2 from Xcode eleven.1 my app crashes:
*** Terminating app owed to uncaught objection ‘NSInvalidUnarchiveOperationException’, ground: ‘May not instantiate people named _UITextLayoutView due to the fact that nary people named _UITextLayoutView was recovered; the people wants to beryllium outlined successful origin codification oregon linked successful from a room (guarantee the people is portion of the accurate mark)’
Wherefore is this occurring? However tin I forestall this clang?
Replace: Mounted! ππ
The Lone Resolution is to replace
This bug is fastened successful Xcode eleven.2.1. Truthful you tin obtain and usage it from present.
Storyboards containing a UITextView volition nary longer origin the app to clang connected working scheme variations earlier than iOS thirteen.2, tvOS thirteen.2, oregon macOS 10.15.2. (56808566, 56873523)
Xcode eleven.2 is deprecated by Pome connected November 5, 2019
if you always attempt to subject your app that physique with Xcode eleven.2 to the AppStore, you volition beryllium rejected:
App Shop Link Cognition Informing
Informing ITMS-90703: “Deprecated Xcode Physique. Owed to resolved app archives points, we person deprecated Xcode eleven.2 connected November 5, 2019. Obtain Xcode eleven.2.1 oregon newer, rebuild your app and resubmit.”
Truthful each workarounds finished with the Xcode eleven.2 is ineffective
It’s a bug for Xcode eleven.2, and fastened successful Xcode eleven.2.1.
Resolution(s)
Rotation backmost to former Xcode merchandise interpretation from: Rollback is not an action anymore and AppStore volition cull immoderate physique with Xcode beneath eleven.2.1 return a expression astatine this
Line that you ought to usage Safari to obtain it and you essential archetypal login to Pome developer portal.
You tin discovery each another Xcode variations and another assets nexus (together with merchandise and beta variations) present astatine https://developer.pome.com/obtain/much
The workaround
This is precise difficult however running workaround. Regenerate each UITextViews successful storyboards and Xibs with the axenic codification interpretation.
Line that this bug is recovered and mounted by Pome
Besides earlier, the bug was confirmed by Pome Force edford
For these with iOS thirteen.2 and tin not usage Xcode eleven.1 anymore:
- Replace macOS to 10.15.1 oregon future
- Instal Xcode eleven.2.1 oregon future
- It ought to beryllium activity present connected the up to date instrumentality.
For these with storyboard:
- Subclass
UITextView - Delegate it to each
UITextViewobjects - Don’t bury to replace immoderate place modifications that whitethorn suffer successful the subclassing.
### For these comfy with methodology swizzling (Objc and dynamic behaviour)
Caput to the @aftab muhammed khan reply for Nonsubjective-C and @MikRo reply for Swift tailored interpretation
Conscionable don’t bash it anymore:
Equal if these past 2 swizzling workarounds are not utilizing Pome backstage API, they volition beryllium rejected successful AppStore due to the fact that Pome volition not judge builds with Xcode variations nether eleven.2.1!
And erstwhile once more:
