Hey, good news! I made progress with iOS! When I deleted the VALID_ARCHS before, I had deleted them only in the general project, and it finally dawned on me to look at the settings for the cocos target. Once I did that, I’m now able to at least partially launch in the simulator. Now I’m running into a problem with AudioEngine, so I’ll work on that tomorrow.
Also, I’m working with xcode 11.6, so I’ll probably create a duplicate project tomorrow and try xcode 12.4.
Thanks again @smitpatel88 ! I’ll let you know how it works out.
