I have a mixed-language project that began in Objective-C, but later we started using Swift for new classes.   In the Objective-C code, there is a custom collection view cell with its own XIB file. When used from a view controller that is also in Obj-C, it works fine.   However, when we try to use the cell in a Swift view controller, we see this… (Show more)

Hi,   Is there any framework or function in iOS that can do tempo detection on an audio sample and/or an audio stream?   I'm currently doing this using a third-party library written in c++, but it is cumbersome and I want to get away from it if I can.   Thanks, Frank

Is it possible for an app to search the iTunes catalog and assist the user in buying a song?   Even if I have to open a different app to do the actual purchase, this would be OK as long as I could do the searching inside my app and send the other app a unique ID of the song to be purchased.   I think I remember reading that this was possible… (Show more)

I submitted an app on Saturday the 21st. It is still in the "Waiting for review" state. Does this mean that nothing will happen until they re-open after the holiday shutdown, or do they still review apps that were submitted before the deadline?   Frank

Is it safe to delete archives from the finder? That is, from ~/Library/Developer/Xcode/Archives?   I have a lot of them, and it's tedious to remove them from Xcode because you can only do it one at a time, and there is a confirmation prompt.   I also have a number of empty directories that correspond to old projects I no longer maintain. I can't… (Show more)

Help,   I've been handed an Xcode workspace that contains projects in Swift 3 and other projects in Swift 5.   If I open the workspace in Xcode 10.3 or later, it says that the Swift 3 projects aren't supported anymore and I should open them in Xcode 10.1.   If I open the workspace in Xcode 10.1, it doesn't recognize the Swift 5 project and… (Show more)

I can't figure out why I'm getting a CBManagerState of "unsupported" when I try to use Bluetooth in my app.   I checked the box that says "Uses Bluetooth LE accessories" in the Signing & Capabilities panel, and I added both of the privacy keys to my info.plist file.   When I first ran the app, it askedme whether I wanted to allow it to use… (Show more)

I do work for a customer who invited me to their team several years ago and gave me full access to do both development and app publishing. Recently, something went wrong, and I no longer have any access to their account in Xcode or on the Developer web site, although I still have access through iTunes Connect.   I've gone back and forth with this… (Show more)

How do I configure an iPad app to only work in portrait mode?   In Xcode there are checkboxes for the four orientations, and only Portrait is checked, but the app still rotates into landscape mode.   I also tried checking the "Requires full screen" box, but this didn't have any effect.   Thanks, Frank
