Fuzzy String Matching (BK Tree)
// Fuzzy string-matching algorithm
// Implementation of algorithm described at: http://blog.notdot.net/2007/4/Damn-Cool-Algorithms-Part-1-BK-Trees
// Essentially builds an index of strings by levenshtein distance (N-ary tree) on which you can run range queries.
// The root node can be chosen arbitrarily. Each node holds a string and a collection of edges, representing distance to other strings, which then have their own children and so on, building a complete index.
// See https://github.com/vy/bk-tree for (impressive) performance statistics despite this tending to create an unbalanced N-ary tree

var value: String
var edges: Dictionary<Int, BKTreeNode>

How to symbolize OSX crash logs

How to Symbolize OSX Crash Logs

Unfortunately, xcode does not yet have support for importing OSX crash logs and symbolizing them. Therefore, you must use the command line and a little bit of manual work.

  1. Find your dSYM file.
    1. Assuming you are using xcode's archive functionality, open the Organizer window from the Window menu.
    2. Click the Archives tab.
    3. Right click on the appropriate build and select Show in Finder.
    4. When Finder opens, right click on the selected archive and select Show Package Contents.
    5. Navigate to the dSYM directory and copy the appropriate dSYM file to a temporary directory.
  2. Then navigate to Products, then Applications, and copy the app file to the same temporary directory.
