What version of sqlite does iOS provide?

Question

What version of Sqlite does iOS include?

Answer 1

Use following to printout the version in your code. You may define following as a separate debug only function and call it from didFinishLaunchingWithOptions in your appDelegate.

#if DEBUG
// Int representing version; e.g. "3016000" for macOS 10.12.4
int sqliteVersion = sqlite3_libversion_number();
NSLog(@"Sqlite Version: %d", sqliteVersion);

// String representing version; e.g. "3.19.3" for iOS 11
const char *sqliteLibVersion = sqlite3_libversion();
NSString *sqliteLibVersionStr = [NSString stringWithUTF8String:sqliteLibVersion];
NSLog(@"Sqlite Lib Version: %@", sqliteLibVersionStr);

// String representing sourceId; e.g. "2017-06-27 16:48:08 2b09...2e2377b" on iOS11
const char *sqliteSourceid = sqlite3_sourceid();
NSString *sqliteSourceidStr = [NSString stringWithUTF8String:sqliteSourceid];
NSLog(@"Sqlite SourceID: %@", sqliteSourceidStr);
#endif

Alternatively, look at sqlite3.h directly in Xcode. For iOS 11:

#define SQLITE_VERSION        "3.19.3"
#define SQLITE_VERSION_NUMBER 3019003
#define SQLITE_SOURCE_ID      "2017-06-27 16:48:08 2b09...2e2377b"

sqlite3.h also has other methods that can be used for debugging purposes.
