Localization in Swift (support multi language)
what is localization?
is a process of making your app support multiple languages.
First lets start with static elements in main storyboard
Storyboard Localization
Simple login Screen before and after localization
1- Choose language
after add your localized language for me (Arabic (ar) language)
xcode allow you to choose files and reference language to create localization .
by default will create localized file for
1-Main.storyboard
2-LaunchScreen.storyboard
2- Edit Main.strings file (translate words)
3- Test your application
if your run application in simulator you need to change system language to localized language in my case it will be Arabic.
if you run application in your device you also need to change your device language to test application
Now you are ready to run your app ^_^
what if i want to add a new localized object to storyboard?
in this case you all you need to go to Main.strings
“ObjectID.property” = “text”
in Main.strings
as we see this way used with static data, what about dynamic data?
NSLocalizedString for Localization
dynamic way to use localization can used with (Alert-data from API-dynamic text or text than depend on code … etc )
Let’s see simple example with lable and you can apply the same way with different cases.
We will use the concept of key and value pairs you can access the string using a key.
“key” = “value”
Let’s start
1- Create Localizable.strings file
this file will contain key and value of string
File > New > File
now you will see empty file called Localizable.strings
you need localizable file for each language Xcode will create them for you all you need to do select Localizable.strings file will choose language in that way
2- Select Localizable languages
After check localization language X-code will generate file for each language.
3- Edit each file
All you need to use the same key in all files but with appropriate value according language
4- Use in my code (NSLocalizedString)
now you can use dynamic localization and test it.
