Xcode 13 Beta 3 & IOS ipad 15 beta 4, RealityKit crash

Hey

Uhh I though by updating to latest version I will have... "stabler" time... anyway I jumped down from Xcode beta4 to beta3, I can compile the app. But when I run it on ipad, I get > xcode 13 beta 3 Ipad os 15 beta 4

  Referenced from: /private/var/containers/Bundle/Application/DB6BF949-41A0-4824-A01F-637B90443A4C/myApp.app/myApp  Expected in: /System/Library/Frameworks/RealityFoundation.framework/RealityFoundation

What do I dooo ? :- (

I face the same issue: Can't import RealityKit on Xcode Version 13.0 beta 4 (13A5201i)

When I went back to the beta 3,

  1. Make sure I'm opening the Xcode 13 Beta 3
  2. Clean the build folder by shift + cmd + k or Product/Clean Build Folder
  3. (Optional) Delete the contents in /Users/YOURCOMPUSER/Library/Developer/Xcode/DerivedData

Then, I can compile the app with Xcode 13 Beta 3 again

Hope this help

  • @chatdep yep I saw your post & downloaded the Xcode beta 3 from 4 - thank you! But I still cant get it to run! It compiles/runs just fine but then it crashes on the ipad! :- (((( """ dyld[856]: Symbol not found: _$s17RealityFoundation23PhysicallyBasedMaterialV9BaseColorVAA02__E17ParameterWithTintAAWP Symbol not found: _$s17RealityFoundation23PhysicallyBasedMaterialV9BaseColorVAA02__E17ParameterWithTintAAWP """ I'm gonna have a full blown mental breakdown in about 15 mins now.

The dyld issue is expected, since we have changed the APIs a bit between seed 3 and 4, so there is a symbol mismatch that occurs when compiling with the old APIs and running on a device with the new APIs. If you can, I would download iOS 15 seed 3 to match your Xcode version if you can, or wait for seed 5.

  • Hai, I went over change-log for ipados5 but I did not see any mention of it, so did the xcode reality kit bug & this one here above got fixed in v5 maybe? TIA

  • @Dariusz1989 this dyld issue should be resolved by having the same Xcode and iPadOS seed builds. Additionally, the Xcode RealityKit bug should be fixed in seed 5, however I saw another developer hitting more Catalyst/RealityKit bugs in seed 5. That bug is being worked on. So I would proceed with caution to seed 5 for now, if you don't have two devices to install seed 3 and seed 5 separately on, I would wait for seed 6.

  • Amazing thank you so much for getting back to me! I'll wait for Seed6 in this case. I've upgraded my xcode to 5 and it looks like its compatible with IpadOS4, so I can keep developing. still some functions are broken so I have // them away for now. WIll reply here when 6 is out to 2x check again :- ) Thank you again! Also update, seems like the functions that were broken in xcode Beta 3 are working in xcode beta 5 yay!!!
