Debugging is the process of detecting and removing computer program bugs. To correct errors, software developers use debugging tools.
Remote debugging means that you use your local debugging tool to correct the defective code running on a remote machine.
To debug an application remotely, programmers use special tools that support the remote debugging feature. They start the debugger on the local computer and launch the program in debug mode on a remote machine. Then, connect the debugger to the remote computer via a communication port. Once connected, the debugger is able to control the execution of the program on the remote system and retrieve information about its state.
When it comes to testing and debugging of mobile applications, the important element is target devices. Well, if you have the possibility to connect a phone, tablet, etc. directly to your development machine, you don’t have to worry. But what if you needed to inspect an app running on a device which couldn’t be physically connected to your Mac? Remote debugging will probably be the best option in that case.
If you are wondering how to debug iOS app on a device, we’ll tell you about the simplest way. Wireless debugging has become a reality thanks to the new feature available in Xcode 9.
This feature eliminates the need to always connect and disconnect the device for app installation and debugging.
However, you should bear in mind that, despite its many advantages, this method has some major flaws:
FlexiHub is designed to virtualize USB devices, (like iPhone, iPad, iPod, etc.) and redirect them over the network. The solution works across LAN, Ethernet, and the Internet.
Here’s how FlexiHub can help you access and debug iOS app on devices remotely:
That’s it. Now you can access the remote iOS device from your local computer as though it were directly connected to your machine.
If you still want to go with the wireless debugging presented in Xcode 9, below you will find a brief step-by-step guide.
Before you start, make sure that you use Xcode 9.0 or later, macOS 10.12.4 or later, and iOS 11.0 or later.
To set up iPhone, iPad, or iPod touch, follow these steps:
Now, Xcode will pair with your device. If Xcode can connect with the device over the network, a network icon will appear next to the device in the left column.
Now you are ready to start remote debug of iOS apps.
