Application capacity is unusually large

If you simply install it with the Run button of Xcode, I think the capacity displayed there is reasonable.When I transferred a project from Xcode that was still in the initial template where nothing was added, the capacity was about that much (39MB in my environment).

Application capacity varies depending on debug build, binary to upload to AppStore, and actual delivered binary.

There is a way to check the capacity of the application when it is actually delivered, so please refer to the other answers below for more information.You'll see that it's actually going to be smaller.

When I exported an application built with Firebase and AdMob added to the initial state template in my environment, the size was 10.2 MB uncompressed and 3.4 MB compressed, and when I installed the IPA file on the device, the iPhone storage screen was 10.2 MB.
Now that we've seen the same thing in the initial state, Firebase and AdMob will increase capacity by about 3MB, and the entire app will be at least 10MB in size.
