Get People Name and Phone Number from Contact by Swift

11 Comments

It’s time to learn Swift. After Swift first release in 2014, now more and more people start using Swift as their program language in iOS. Therefore, I decide to use Swift in my current project, loading people first name, last name and phone number from contact. This will be a good project to learn Swift from beginning.

When we create new project in Xcode, it will use Swift language by default. The only different between Objective-c and Swift is there is no .h and .m file any more. There is only one .swift file which we can declare class inside. In my new project, there is only two .swift file. One is AppDelegate.swift; the other one is ViewController.swift. All my logic to get people information from contact are in ViewController.swift. Now, I will start to show you how to get people first name, last name, and phone number from contact. All example source code will use swift.

Christmas is fast approaching. And whenever this season of the year comes, the first thing that comes to my mind is making a list of presents that I plan to buy for each member of my family. I’m an avid fan of android tablets. However, it will not be a perfect gift for my wife since she loves iPad more. Perhaps it’s because my wife is a teacher and the iPad comes handy and very useful in the practice of her career. Aside from my wife, I also need to prepare a gift plan for my two old parents as well.

Though there are many varieties of tablets in the market. But there are only 4 main types of tablets we can buy.

After I release a free web server, my PHP server is suffering from resource exhausting problem. The main problem is my server disk storage over quote. The problem is too serious because after the disk is full, I cannot login the cPanel. After that, all my website is down. As I am saving session in the file. After the disk is full, the login function doesn’t work any more because session cannot create new file to save the data.

The only solution for this situation is updating my server or finding a way to keep disk having enough space. Because of the budget issue, I don’t have enough money to upgrade server. So the only way to solve problem is keeping the disk having enough space all the time.
