Hey I had a similar issue. i got a solution. my problem was this: for some reason app was showing up in simulator and on old iphone, but would just show black screen on this new iphone I added. Was also seeing something about "code signature invalid" in the mix. Along the lines of this:dyld: Library not loaded: @rpath/Mapbox.framework/Mapbox Referenced from: /private/var/containers/Bundle/Application/EC52D3BB-17AC-4957-9AF5-EDC3860DC7A5/WalkBuddy.app/WalkBuddy Reason: image not found Mapbox SDK 5.7.0ios version 13.4xcode 11.4-Deleted app off phone, cleaned build and removed old profiles(found in ~/Library/MobileDevice/Provisioning Profiles)-Deleted everything in "iOS DeviceSupport" file found in '~/Library/Developer'.-Cleaned derived data.-In keychain I deleted all my certificates.Also removed my account and re-added it upon re-starting xcode (IMO this might have done nothing, but worth adding). Restarted phone and xcode. App is up and running on my phone now! And no I do not have paid account right now.MaybeI took too many steps but whatever I did worked! Also podfile looks like this :platform :ios, '13.2' target 'WalkBuddy' do use_frameworks! pod 'Mapbox-iOS-SDK', '~> 5.7.0'
