Application installation file
Anyone can try their hand at creating software for iOS devices; all you have to do is create or buy an Apple developer account, and then understand the procedure and master useful tools. The latter includes the iOS App Store package, or IPA file. In fact, it is an analogue of an APK and allows you to test the program after installation on the device. For those who have not worked with application archive files before, Nova.Shop specialists have prepared a description of the key points.
The IPA file itself resembles a ZIP folder, inside of which the information that constitutes the utility is collected. If you wish, you can even publish it in the official store before the main launch to make sure there are no bugs and get feedback from real users.
How can iOS app Developer receive and open IPA file?
There is no particular need to open the folder with data about the utility; it is used at the stage of checking the design and functionality of the application by sending it directly to the official store. But technically there is such a possibility, and in several ways:
- Use 7-Zip or Winzip to unzip and view the internals. After opening, you will be able to see individual files and folders, as well as the utility icon, but you will not be able to launch the software.
- In the new version of iTunes, opening is performed using Diawi and other third-party tools.
- If you have an older version of iTunes installed, then you need to open Mobile Applications in the iTunes Media folder, which is located in the Music section. On Mac devices, the transition occurs from the main menu, and when using the Windows operating system, you first need to open the C drive and then go to the Users folder.
IPA file contents
The structure of such files is identical to Apple and consists of:
- WatchKitSupport/WK;
- iTunesMetadata.plist;
- iTunesArt-file;
- Application.app file;
- Payload;
- iTunes fileWork.
The IPA file performs the function of transporting key information about the utility, including:
- detailed information about the software (located in the Payload folder);
- PNG icon image (iTunes Artwork);
- metadata about the utility with which the application was developed (META-INF);
- Developer and package ID, title, launch date, copyright information (.plist).
How can an Apple Developer account owner create an application archive file?
Generation can be complex for an inexperienced programmer, but there are ways to simplify it. The traditional way of creation is to prepare a project from scratch in Xcode and then export it. If you don’t have enough knowledge for this, you can use the AppMySite platform; by the way, in this case, immediately after downloading the finished assembly, you will be able to place the digital product in the official application store. The only thing is that you will need to first buy an Apple developer account or register in the system and pay for the subscription.
Without access to tools for developers, it is impossible to generate an application archive file, much less publish the software.
Installation process on the device
After the Developer account iOS receives the IPA file, he has the opportunity to preliminary study the software to evaluate the visuals and functionality of the created utility. The choice of installation tools is quite large, but most developers use TestFlight – this is a convenient utility that allows you to install an assembly on a device and then run it. It’s easy to use:
- log into your App Store Connect profile;
- specify certain users as internal testers, after which they are sent an appropriate invitation by email. These do not have to be iOS accounts with paid games; you can select any user of Apple brand products with an active account;
- after confirming consent, the option to write an activation code and install TestFlight on the device appears;
- Using a testing tool, all that remains is to download the application archive file, and then begin to analyze its usability and performance.
When creating Apple programs using AppMySite, the owner of the developer account can examine the result of his work in another way – using Preview. This section contains an emulator that allows you to check the compliance of the original idea with the actual design and functionality. An additional plus is the option of switching between emulators to evaluate the application’s performance on different Apple gadgets.
Ability to convert to APK
No iOS Developer will be able to fully transform one file type into another. IPA and APK are used for devices with different operating systems, respectively, they have completely different structures. In theory, you can manually rename the file indicating the extension of interest, but the maximum that can be achieved is extracting the source code for subsequent writing of a program for the Android OS. One way or another, you will need different assemblies when working on utilities for different environments.
In general, working with IPA files does not require superpowers and can be very useful, allowing the developer, after registering as an Apple Developer and creating software, to test it on real devices. You just need to understand how to obtain, open and install them, and we hope that our review helped to understand this.
