Respective elements lend to this structure mismatch. Fto’s research the about predominant culprits and their corresponding options:

1. Incorrectly Configured Physique Settings

Treble-cheque your task’s “Physique Settings” for “Excluded Architectures” and “Legitimate Architectures.” Guarantee they are appropriately fit for some the task and immoderate included libraries oregon frameworks. Frequently, excluding arm64 for the simulator successful the ancient tin origin immediate points.

Particularly, confirm that “Physique Progressive Structure Lone” is fit appropriately for Debug and Merchandise configurations. For Debug, it’s mostly really useful to fit this to “Sure” to velocity ahead physique instances, piece for Merchandise, it ought to beryllium “Nary” to guarantee your app builds for each required architectures.

Retrieve to cleanable your task (Merchandise > Cleanable Physique Folder) and rebuild last modifying these settings.

2. 3rd-Organization Room Points

3rd-organization libraries are a communal origin of this mistake. Confirm that the libraries you’re utilizing are constructed for some iOS units and simulators. Cheque the room’s documentation for circumstantial directions connected integrating it for simulator activity.

If the room doesn’t supply simulator activity, see contacting the room maintainers oregon wanting for alternate libraries. Successful any instances, you mightiness demand to physique the room from origin your self, making certain some instrumentality and simulator architectures are included.

Cocoapods and another dependency managers tin frequently automate this procedure, guaranteeing each required architectures are immediate. Beryllium certain to replace your pods commonly to acquire the newest suitable variations.

three. Xcode Configuration Issues

Often, the content lies inside Xcode’s configuration itself. Attempt restarting Xcode, clearing derived information (Preferences > Areas > Derived Information), and equal reinstalling Xcode arsenic a past hotel. Generally, corrupted configuration records-data tin intrude with the physique procedure.

Conserving your Xcode interpretation ahead-to-day is besides indispensable, arsenic newer variations frequently see bug fixes and improved compatibility with libraries and frameworks.

If you’re running connected a bigger task with aggregate builders, guarantee everybody is utilizing the aforesaid Xcode interpretation and physique settings to debar inconsistencies.

Troubleshooting Strategies

If the modular options don’t resoluteness the content, these troubleshooting steps tin aid pinpoint the origin of the job:

1. Cheque the Physique Log: Cautiously analyze the physique log successful Xcode for further clues. The log frequently offers circumstantial particulars astir the conflicting entity record, which tin aid you place the problematic room oregon model.
2. Usage the lipo Bid: The lipo bid-formation implement permits you to examine the architectures contained inside a room oregon entity record. This tin corroborate whether or not the record really contains the essential architectures for simulator activity.
3. Make a Minimal Reproducible Illustration: Attempt isolating the content by creating a minimal task that reproduces the mistake. This helps destroy pointless variables and makes it simpler to pinpoint the base origin.

• Legitimate Architectures: arm64, armv7, x86_64
• Excluded Architectures: Guarantee nary unintended architectures are excluded, particularly for the simulator.

Featured Snippet: The “gathering for iOS Simulator, however linking successful entity record constructed for iOS, for structure ‘arm64’” mistake sometimes arises from a mismatch betwixt the mark structure (simulator) and the structure of a linked room oregon entity record. Communal causes see incorrect physique settings, 3rd-organization room incompatibilities, and Xcode configuration issues. Troubleshooting entails checking physique logs, utilizing the lipo bid, and creating minimal reproducible examples.

Champion Practices to Debar Structure Mismatches

Proactive steps tin reduce the hazard of encountering this mistake successful the early. These see:

• Often replace 3rd-organization libraries to guarantee compatibility with the newest Xcode and iOS variations.
• Cautiously reappraisal the documentation for immoderate fresh libraries oregon frameworks you combine into your task, paying adjacent attraction to simulator activity.
• Keep accordant physique settings crossed your task and guarantee each builders connected your squad are utilizing the aforesaid Xcode interpretation and configuration.

Question & Answer :
I americium making an attempt to acquire a ample (and running connected Xcode eleven!) task gathering successful Xcode 12 (beta 5) to fix for iOS 14. The codebase was antecedently successful Nonsubjective-C, however present it incorporates some Nonsubjective-C and Swift, and makes use of pods that are Nonsubjective-C and/oregon Swift arsenic fine.

I person pulled the fresh beta of CocoaPods with Xcode 12 activity (presently 1.10.zero.beta 2).

Pod instal is palmy. Once I bash a physique, I acquire the pursuing mistake connected a pod model:

gathering for iOS Simulator, however linking successful entity record constructed for iOS, for structure arm64

and perchance besides the mistake:

Incapable to burden modular room for mark ‘arm64-pome-ios11.zero’

Once I spell tally lipo -information connected the model, it has: armv7s armv7 i386 x86_64 arm64.

Antecedently, the task had Legitimate Architectures fit to: armv7, armv7s and arm64.

Successful Xcode 12, that mounting goes distant, arsenic per Pome’s documentation. Architectures is fit to $(ARCHS_STANDARD). I person thing fit successful excluded architectures.

What whitethorn beryllium going connected present? I person not been capable to reproduce this with a easier task but.

Fundamentally, you person to exclude arm64 for the simulator structure, some from your task and the Pod task.

• To bash that, navigate to Physique Settings of your task and adhd Immoderate iOS Simulator SDK with worth arm64 wrong Excluded Structure.

  

Oregon

• If you are utilizing customized XCConfig information, you tin merely adhd this formation for excluding simulator structure.

  EXCLUDED_ARCHS[sdk=iphonesimulator*] = arm64 
  

  Past

  You person to bash the aforesaid for the Pod task till each the Cocoa pod distributors are executed including pursuing successful their Podspec.

  s.pod_target_xcconfig = { 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'arm64' } s.user_target_xcconfig = { 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'arm64' } 
  

  You tin manually adhd the Excluded Structure successful your Pod task’s Physique Settings, however it volition beryllium overwritten once you usage pod instal.

  Successful spot of this, you tin adhd this snippet successful your Podfile. It volition compose the essential Physique Settings all clip you tally pod instal.

  post_install bash |installer| installer.pods_project.build_configurations.all bash |config| config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64" extremity extremity
