This allows you to share patterns with other sets and projects easily but also means that if you edit a pattern you re changing the rule for every batch finds options set everywhere. When in doubt create a new pattern. To the left of each pattern is the Include Exclude control that determines whether the pattern must match or not match a filename to be included in the set. For a file to be included in the search its name must satisfy all of the checked regular expression patterns in the list. If the list has the two patterns Include .m and Include .h both checked then no files will be searched there is no filename that will match both .m and . h . In general use at most one Include pattern to define the principle group of files to consider and then use additional Exclude terms to winnow out unwanted files. SEARCH PATTERNS The various Find commands all apply a search pattern to the text of your files in order to find the text that matches the pattern. Xcode gives you a lot of flexibility in specifying the parameters of your search from a simple unanchored literal text string to complex
