What a beautiful song!...it's giving me chills
the tabs I found wasn't sounding right to my ears so that's my version
these are only the basic chords but use fantasy as you wish...

Capo on 3

Intro:
C  F


Verse:       
    C        
You gotta swim 
               F
Swim for your life
               C 
Swim for the music 
That saves you 
                                  F
When you're not so sure you'll survive 
           C
You gotta swim 
                   F
And swim when it hurts 
                     Am
The whole world is watching 
You haven't come this far 
                  F
To fall off the earth 
    G
The currents will pull you 
                F
Away from your love 
Just keep your head above 

Chorus:
C
I found a tidal wave 
G                         F
Begging to tear down the dawn 
C
Memories like bullets 
G                        F
They fired at me from a gun 
(G)
Cracking me open yeah 
C                    
I swim for brighter days 
G                       F
Despite the absence of sun 
(G)
Choking on salt water 
F    C         G
I'm not giving in 
    C
I Swim


F      C     F

Verse2:
           C
You gotta swim 
                       F
For nights that won’t end 
                  C
Swim for your families 
Your lovers your sisters 
                    F
And brothers and friends 
                  C
Yeah, you gotta swim 
                   F
For wars without cause 
                       Am
Swim for the lost politicians 
                                F
Who don't see their greed is a flaw 
     G
The currents will pull us 
                F
Away from our love
Just keep your head above
 

Chorus  2:
C
I found a tidal wave 
G                         F       (G)
Begging to tear down the dawn 
C        
Memories like bullets 
       G                 F
They fired at me from a gun 
(G)
Cracking me open yeah 
C
I swim for brighter days 
G                       F
Despite the absence of sun 
           (G)
Choking on salt water 
F    C         G
I'm not giving in
F    C             G
But I'm not giving in 
    C
I Swim


Solo:
F        C         G
           

Final Verse:
           C         
You gotta swim 
             F
Swim in the dark 
                     C
There's an ocean to drift in 
                                       F
Feel the tide shifting away from the spark 
                C
Yeah you gotta swim 
                    F
Don't let yourself sink 
                  Am
Just follow the horizon 
                                       F
I promise you it's not as far as you think 
G                                        F
The currents will drag us away from our love 

                        C    F
Just keep your head above 
                        
Just keep your head above 
C   F
Swim              
Just keep your head above 
C  
Swim
F
Swim 
Just keep your head above 
C   F
Swim
