App crashes initializing map with MapView(frame: .infinite)

[teradyl]

Environment

• Xcode version: 16.0
• iOS version: iOS 18.0 & iOS 17.5 (seems only on simulator)
• Devices affected: Simulator. Tested iPhone 16 Pro (iOS 18) & iphone 15 Pro (iOS 17.5)
• Maps SDK Version: 11.7.0

Observed behavior and steps to reproduce

running MapView(frame: .infinite) crashes the app.

Expected behavior

I can create a map with infinite frame, or if not it doesn't crash!

Notes / preliminary analysis

I didn't have an iOS 18 device to test on yet, but my iOS 17.5.1 device did NOT crash on this. Here is the stacktrace of the crash on the simulator, however:

*** Terminating app due to uncaught exception 'failed to resize: size is empty', reason: 'failed to resize: size is empty'

Thanks for reporting this @teradyl. I've been able to replicate this issue on my side. I'm taking this back for discussion with the broader team.

Hi @teradyl --

Can you share a bit more about your use case here? Why are you setting an .infinite frame?
