  • Debugging Swift Objects in LLDB

    Given an address of the object, one can interact with it via LLDB. To do this, you need to import the corresponding module (like UIKit, or your app’s module) and then cast the address to a new variable using Swift’s unsafeBitCast like this:

    (lldb) expr -l Swift -- import UIKit
    (lldb) expr -l Swift -- let $view = unsafeBitCast(0x7fb75d8349c0, to: UIView.self)

    When it came to building an app with a login screen I got a bunch of questions. And I found some answers to them scattered all over the Internet. It might seem an obvious task, but I really wanted to find a guide with some clarifications. I wasn’t lucky enough to do that so I decided to describe my way of building a [first] login view myself.

  • Xcode 7 and Github with SSH Keys authentication

    I had been working a lot with PHPStorm and RubyMine when I came to Xcode this summer. All the JetBrains tools work with git remote hosts, Github and Bitbucket, quite well. But when I tried to access my repositories with the ssh key from Xcode I received an error: “Authentication failed. Username or password incorrect”.

  • First Android App

    I’ve finished a beta of my first Android app for internal use, a front office system for the Cafe owned by our company. It has 6 thousands lines of code, I’ve spent 170 hours for immidiate development of it.
