swift - Is it possible to set a struct as target for NSTimer -

-

i trying set scheduledtimerwithtimeinterval inside struct keep getting error cannot invoke scheduledtimerwithtimeinterval argument list of type. when change struct class works fine.

my question possible set struct target of nstimer? api says should of type anyobject

struct mytimer{     init() {         let timer = nstimer.scheduledtimerwithtimeinterval(1, target: self, selector: selector("timer"), userinfo: nil, repeats: true)     } }

and 

class mytimer{     init() {         let timer = nstimer.scheduledtimerwithtimeinterval(1, target: self, selector: selector("timer"), userinfo: nil, repeats: true)     } }

edit: seems class target of scheduledtimer has inherit nsobject first. struct never that.

mysql - FireDac error 314 - but DLLs are in program directory -

i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.
