List of mostly used git commands
Quite often we need to have multiple target for xcode project to handle development version, UAT version or production version. But if you are using pod project then you might get error such as “No module found” for specific target and no issue with other target. This generally happens when we misconfigure Podfile. So here’s how we can install same pod file for multiple target.
Many times we find it difficult to figure out why the IPA installation failed when using ad-hoc installation link. A possible reason may be your device UDID is not included in the distribution profile. Here’s how to verify if your UDID is included in iOS Distribution profile.
- Generate ad-hoc IPA from Xcode.
- Cd to IPA file.
- Run Command: unzip <appname>.ipa. This will extract the content of ipa to Payload folder
- cd to Payload.
- cd to <appname>.app
- open embedded.mobileprovision in TextEditor.
- Or Run command: security cms -D -i ./embedded.mobileprovision
- Look for <key>ProvisionedDevices</key> or <key> UDID </key>
- Your device udid must be listed there.
Choosing right color in application make it elegant, but achieving this is not an easy task. For this, we need a support from best designers. In the same time even designer cannot achieve the best layout and design in one shot. He needs to keep trying with the different color theme and figure out the best one. This is the normal process of application design, but reflecting this via coding is even tough task especially when color theme keeps changing.time even designer cannot achieve the best layout and design in one shot.

- From Xcode menu open: Product > Scheme > Edit Scheme
- On your Environment Variables set
While developing an app that requires an internet connection, it is very important to handle use-cases when the connection is slow or non-existent. To figure out when there’s a bad connection via your code, you can use this great Reachability library.
Once Reachability is implement it, it’s pretty easy to test it by simulating a bad connection on your iPhone or iPhone Simulator if you know what tools to use. Here is how you can test a your app on different internet connections using your iPhone and iPhone Simulator:
SQLite is a C library that implements an SQL database engine. It is a Relational Database Management System (or RDBMS). Most of the SQL databases work with the client/server model. Take MySQL for an example. To enter and receive data from a MySQL database you need to send a request to the MySQL server, which on reception will provide you with the appropriate response. Contrary to MySQL, SQLite databases are operated directly from the disk. There is no need to create requests to the server.
